The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up.
We’re in for a solid run of decent-to-good conditions at Jaconé over the next couple of weeks, but it starts with a real bang for experienced surfers. The water’s sitting at about 73°, pretty much normal for this time of year, so no surprises there.
The opening act kicks off Tuesday afternoon, August 25, with a solid 8ft southerly swell. The combined energy is pumping hard at (2122). That’s a lot of juice. Winds are light cross-off, so the waves will be clean, but this is serious size – over 8ft territory is for experts only. Wednesday morning, the 26th, drops a touch to 7ft but the swell period is a nice 12 seconds and winds stay light cross-off. Still heavy stuff. Wednesday afternoon picks back up to 8ft with a very long 15-second period from the south, and energy jumps to (3162). That kind of period at a beach break can make things a bit straight, but the power is undeniable.
Thursday morning the 27th is similar: 8ft of south swell, 14-second period, light north winds, clean. By Thursday afternoon the wind picks up a bit from the east, but it’s still cross-off. Friday the 28th is where things start to get interesting for the rest of us. Morning brings a clean 4ft south swell with offshore northeast winds at 9 mph. It’s glassy and clean, and energy is still moderate (574). That’s a standout window for intermediate surfers – decent size, clean faces. The afternoon gets smaller and windier, so hit it early.
Saturday the 29th morning offers another clean offshore option with 6ft from the east-northeast, but the period is short at 8 seconds. That’s a weaker, more windswell-type wave. Still, offshore wind makes it rideable.
Then we hit a dry spell. From Sunday the 30th right through to Tuesday the 1st of September, the swell drops below 3ft, winds go onshore or cross, and energy is weak. It’s a proper gap of poor surf, almost three full days of nothing worth paddling out for.
Wednesday the 2nd kicks back up but it’s messy – strong west-southwest winds, rain, and a short-period 5ft swell. Not your friend. Thursday the 3rd morning is a huge standout for the brave: a glassy 10ft south-southwest swell with a 10-second period, energy at (1454). The notes say it might be too big even for this break, but if you’re an expert and after a big clean day, this is it. The wind is flat calm – glassy. Afternoon drops to 8ft, still clean with cross-off winds.
From Friday the 4th through Saturday the 5th, we get onshore winds and dropping swell – not great. Sunday the 6th morning brings a clean 3ft south swell, light cross-off breeze, and it builds through the afternoon to 4ft. Good for the longboard or a fun small-wave board. Monday the 7th morning is even better: offshore winds, 4ft south swell, clean and inviting.
Tuesday the 8th morning is another glassy gem – 5ft of south swell, 12-second period, no wind. That’s a lovely window for a quality session. Wednesday the 9th morning repeats the trick: glassy, 4ft south swell, long 12-second period. Clean and easy paddling.
Overall, the best two true standouts are Friday morning August 28 for intermediates – clean offshore, 4ft – and Thursday morning September 3 for experts only, with 10ft glassy power.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
